As my readers well know, TPP has been encouraging top predators to reside in our estate. This AM our breakfast amusement was watching at close quarters a young red-tailed [?] hawk try to obtain a squirrel for breakfast just outside our kitchen windows. The most amusing aspect was the extreme audacity of the squirrels who feeling invincible when in a familiar tree at times actually aggressively confronted the hawk who was quite confused by it all. What fun! Although on the whole, too bad the hawk was not winning.
